Weegy: In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus (e.g. [ The energy that the Sun emits into space is produced by nuclear reactions that happen in its core due to the collision of hydrogen nuclei and the formation of helium nuclei). During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active or "main sequence" stars.
] User: Does Nuclear fusion occur in stars? Weegy: Sun is a star and all stars are big balls of gas, primarily made up of gargantuan amounts of Hydrogen and Helium. To know what is nuclear fusion and how does it work in the Sun, one must know what are stars made of. [
Nuclear fusion in the Sun is a process by which rapidly colliding nuclei, like those of Hydrogen, fuse together at very high temperatures, to form nuclei of higher atomic weight. In this process some mass is lost and converted into energy. That is the secret of Sun's energy production! The amount of energy obtained from conversion of 1 gm of matter into energy (given by Albert Einstein's celebrated equation, 'E = mc2) would be roughly 9 X 1013 Joules! So matter is just a form of energy! They are two manifestations of the same thing!

Weegy: b. The use of renewable resources is more common and widespread than the use of nonrenewable resources
Gas and oil are nonrenewable resources required for running some rides. A renewable resource would be water. [ Water can be used in lots of places in amusement parks. Water can be used on rides. The water can be used to make a ride well actually run. It can also be used to make a ride more exciting. Splash Mountain at Disney's Magic Kingdom is a ride where you probably are not going to come off dry. It is a very exciting yet wet flume ride. ] User: Which of the following is a social consequence of global fuel dependence?
